The agency says up to 15 awards across four project areas, but Project Area 1 alone carries a $7.8 million ceiling against a $10.8 million pot. That tension is the single most important strategic fact in the NOFO — here is how to read it, which lane is least competed, and what a three-week runway means for your submission.
